Light Pollution Map of the Eastern USA
This light pollution map shows the amount of light pollution on the easter half of the united states. The darker areas on the map have less light pollution. As you can see Spruce Knobb State Park (SN) is in one of the darkest areas east of the Mississippi. It is a great place for observing. Another good location is Cherry Spring State Park (CS). The Black Forest Star Party is a very popular star party held at Cherry Springs.
The dark in this light pollution map areas are the best place to view the stars,
